Time-independent control of the positioning is possible with the aid of the handshake pro-

command. These then take effect immediately with the "Start Positioning" command. The
handshake procedure merely makes sure that the "Target Position Reached" signal is
guaranteed to be reset before the "Start Positioning" command is transmitted.
